Evaluating a new theranostic approach for pancreatic cancer

First-in-human Study of the Theranostic Pair [68Ga]Ga DOTA-5G and [177Lu]Lu DOTA-ABM-5G in Pancreatic Cancer

Early Phase 1 Interventional University of California, Davis · NCT04665947

This study is testing a new treatment for pancreatic cancer to see if a special imaging method can help find the right patients for a targeted therapy that might improve their outcomes.

What this trial studies

This Phase I, first-in-human study aims to assess the safety and efficacy of the theranostic pair [68Ga]Ga DOTA-5G and [177Lu]Lu DOTA-ABM-5G in patients with locally advanced or metastatic pancreatic adenocarcinoma. The study will utilize PET imaging with [68Ga]Ga DOTA-5G to identify eligible patients for treatment with [177Lu]Lu DOTA-ABM-5G. The primary objectives include determining the dose limiting toxicity and the recommended phase 2 dose of [177Lu]Lu DOTA-ABM-5G. An expansion group will also be included to gather initial response estimates and further safety information.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 or older with confirmed locally advanced or metastatic pancreatic adenocarcinoma who have experienced tumor progression after prior treatment.

Not a fit: Patients with pancreatic cancer types other than adenocarcinoma or those who have not progressed after prior therapies may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a new targeted therapy option for patients with advanced pancreatic cancer.

How similar studies have performed: While this approach is novel, similar theranostic strategies have shown promise in other cancers, indicating potential for success.
